Abstract

A calibrator suitable for calibrating a noninvasive analyte detector, such as a Raman spectroscopy device, allows the user of the detection device to establish standard measurements of the analyte to be detected, thereby providing assurance that appropriate analyte measurements are obtained at the time of sampling. The calibrator is simple to use, making it suitable for home use by individuals regardless of medical or technical skill level. In particular, the calibrator can be used with a noninvasive glucose detection system, such as for monitoring of blood glucose levels in diabetics. For use with noninvasive detectors designed for obtaining measurements from a subject's fingertip, the calibrator can be formed into a shape that reasonably mimics a fingertip in size, texture and/or spectral properties.
